Hey everyone,

I have an 03 Chevy Trailblazer LS 4.2. My check engine light has appeared on & off for the past month or so reading the code P0105. I replaced the MAP sensor less than a year ago. I haven't noticed any change in engine idle or power. It will be on for about a day & I'll drive it then it will turn off. I drove all the way to ocean city from philadephia with the light on and back with no problems.

Anyone have any take on this?

Thanks!

 

Well no one could help me.

I scrubbed my throttle body today and reset the system by removing the fuses while I worked. Started it up, the light turned off. We'll see. I guess I'll see since no one cares! Thanks for nothing!!!!!!

 

Those engine codes are really nothing to do with performance. Since you figured it out yourself, consider it a self tutorial.
